Can nylon bolts be used outdoors?
Only UV-stabilized (black) nylon fasteners should be used outdoors. Natural (white/cream) nylon degrades rapidly under UV exposure, becoming brittle within months. UV-stabilized grades last 3-5 years in direct sunlight.
Are nylon fasteners food-safe?
PA6 and PA6.6 in natural color (without additives) meet FDA 21 CFR requirements for food contact. Black/UV-stabilized grades may not be food-safe due to carbon black additives. Always confirm food compliance with the manufacturer.
